PLEASE GIVE IT A THUMBS UP, I SERIOUSLY NEED ONE

CODE-

DATA SEGMENT
         ARR DB 5,3,7,1,9,2,6,8,4       ;Define byte to stote array
         LEN DW $-ARR                      ;Define word(DW)
         MIN DB ?                                ; We are initializing Min DB ? to ? (? stands for blank value).
         MAX DB ?                              
DATA ENDS                           ;End point

CODE SEGMENT
                    ASSUME DS:DATA CS:CODE      ;assume data name given to data segment
START:
             MOV AX,DATA                  ;Move DATA to AX
             MOV DS,AX                      ;Move AX to DATA

             LEA SI,ARR Load effective address which load address of second element into the first element
             MOV AL,ARR[SI]        ; move the value of Array ARR in index of SI register to AL register.
             MOV MIN,AL               ;Mov AL register to Minimum
             MOV MAX,AL             ;Mov AL register to Maximum

             MOV CX,LEN            ;Assign value of 8 to CX (8 is length of array)
REPEAT:                   ; label and all word end with (:)
             MOV AL,ARR[SI]      
             CMP MIN,AL             ;compare for minimum
             JL CHECKMAX        ;check for max

            MOV MIN,AL            ;store min in AL

           JG DONE

           MOV MAX,AL            ;move max value in MAX
DONE:
           INC SI                        ;Increment the address value in SI
            LOOP REPEAT        ;end of loop

            MOV AH,4CH           ;if value is 4ch then return
            INT 21H             
CODE ENDS         ;end of code segment
END START           ; end of program
